Myth: Arizona's defense has struggled because - thanks to a passing offense - it's on the field so much.

Fact: The Wildcats are giving up 374.6 yards per game, sixth-worst in the league. Not bad, though not great either. Arizona is also middle of the road in the league when it comes to number of defensive snaps and opponent time of possession.

Offensively, the Cats have logged the second-most number of offensive snaps in the Pac-10, second to only Arizona State.

Perhaps the most telling statistic is opponent third-down conversions. Foes are converting almost 45 percent of their third-down chances against the Cats, a figure that ranks ninth in the league. Arizona must simply get off the field on third down.

Myth: The Wildcats' offense has arrived.

Fact: As Lee Corso might say: "Not so fast my friend."

The Air-Zona attack is beginning to click, but consider its efficiency numbers.

Coaches would like a touchdown for every 100 yards of offense. Rarely is it attained. For example, the Wildcats have put up 3,516 total yards and 27 offensive touchdowns. That works out roughly to minus-8.2 TDs - eighth in the Pac-10.
